Why Do Molars Hurt When They Come In?

Molars are a type of tooth found towards the back of a baby’s mouth. Infants are born with a complete set of primary teeth hidden beneath their gums, which typically begin to emerge around six months of age. This natural process, known as teething, involves teeth breaking through the gum line. While the eruption of any tooth can cause discomfort, the arrival of molars often presents particular challenges for both infants and their caregivers.

Why Molars Hurt

The primary reason for this heightened pain lies in their physical characteristics compared to other teeth. Molars are larger and possess a broader, flatter chewing surface than the front teeth. This increased size means they exert more pressure on the gum tissue as they push upwards.

The process of a tooth breaking through the gum is not a “cutting” action; instead, the body releases hormones that cause cells in the gum tissue to die and separate, allowing the tooth to pass. For molars, this process involves a larger area of gum tissue, which can lead to more significant soreness and swelling. The duller, wider surface of a molar can make its passage through the gum less efficient, contributing to prolonged discomfort.

Recognizing Molar Teething Symptoms

Parents can observe several indicators that suggest molars are erupting. Increased drooling is a frequent sign, as is swelling and redness in the gum area at the back of the mouth. Infants may also exhibit increased irritability or fussiness, and their sleep patterns might become disrupted due to the discomfort.

A baby may also frequently chew on objects to relieve pressure on their gums. While teething symptoms are typically localized to the mouth and generally mild, some infants might experience a low-grade fever. These symptoms are usually temporary, often subsiding as the tooth fully emerges.

Effective Pain Relief Strategies

Several methods can help alleviate the discomfort associated with molar teething. Offering chilled, but not frozen, teething toys provides a firm, cool surface for babies to chew on. Gently massaging the gums with a clean finger can also provide relief. A cool, damp washcloth can be offered for the baby to chew on.

For significant discomfort, over-the-counter pain relievers for infants may be considered. Infant acetaminophen or ibuprofen can help reduce pain and inflammation; however, it is important to consult with a pediatrician for appropriate dosage based on the child’s weight and age. Certain remedies should be avoided, such as teething necklaces, which pose a choking or strangulation hazard. Topical gels containing benzocaine are also not recommended for infants due to serious side effects.

When to Seek Professional Advice

While teething is a normal developmental stage, parents should be aware of warning signs for professional medical or dental consultation. Symptoms like a high fever, persistent diarrhea, vomiting, or a widespread rash are generally not typical for teething and could signal a separate illness. If a child experiences severe, inconsolable pain that does not respond to common pain relief strategies, this warrants further investigation.

Parents should contact their pediatrician or dentist if symptoms appear unusually severe, or if pain relief proves ineffective. Seeking professional guidance ensures that any underlying health issues are identified and addressed promptly, providing appropriate care for the child’s well-being.
